CAGE-ADJUSTING MECHANISM Eon cEUsHEE-MACHINES.

To all wlw/m. t may concern.' Y

Be it known that we, vWILLIAM H. HART- MAN and GEORGE lV. BoEToN,v citizens of the United States, residing, respectively, at Philadelphia, county of Philadelphia, and State of Pennsylvania yand -Hadd0niield, county of Camden, and State of New Jersey, have invented; new and? useful Improvements in Cage-Adjusting Mechanism for lrusher-Machines, of which the following is a specilication.Y Y y j This invention relates to improvements in crushing and pulverizing machines .designed, chiefly, though not exclusively, for the crushing ofcoal, and in the accompanying drawing a machine suitable for that use is illustrated byrway of example.

In a prior Vpatent to Joseph L. HillenNo.

1,020,501, March 19, 1912, is shown a crushing and 'pulverizing machine of the type to which in the accompanying drawings we have shown our invention applied. In the Y above mentioned patent is"k disclosed a Crusher provided with a casing having therein a Vrotary beater element inclosed by a pivoted-cage; the cage bein adjustable through a rack secured to its free end and meshing with a rack wheel upon a manually rotatable shaft.

This invention has .for its object to provide an improved means 'for positively adjusting the pivoted grinding `cage of suchv machines with relation to the hammers. VIt has been found that when these machines Yare used', there is`a` tendency for dirtand other matter to collect in the adjusting mechanism of the cage, particularly on and between `the teeth of the rackfand pinion Specification of Letters Patent.

as the Figure 1 is a partial, vertical'sectional'. `view Vshowing a Crusher machine withV our F ig. 3 isanfelevational viewzofa detail I of the mechanism, a portion ofthe rack being shown 1n vertical section.

Eig, 471s a daan View aken at right angles to the View shown Yin-F ig. 3 andYV showing moreclearly the meansfor securing the rack to the cage.

Referringto the drawings vmore in detail, 1 indicates thecasing of the machine which mayzbe of any .desired form, and inA which is locatedthe-'hammer carrying shaft 2 having the disk 8 keyed thereto, said disk being Y provided at suitable intervals v with'` the hammers constitute-the, beater elements of thecrusher, and the same are inclosed in Aa l cage 5 pivotedfat one lend (not shown) to the'A Acasing 1 and having attached Vto its free zend* an*` adjustinglrack 7, said rack bein 1 vertically v'reciprocated through a toothed` sprocket .8 keyed to the Ashaft9.V The shaft 9 is manually rotated through the reducingv gears "10, 11th`e`latte`r gearbeing located on thev shaft 12'provided with a'hand'wheel 13.

So muchbof the machine as we have above generally described isolda'nd well known in the artyand is clearly disclosed and V'shown inthe patent above Yreferred to.'` As stated our invention resides in the improvedL type of rack f?, k,sprocket `8,. andthe meansfor at-y -ftaching'the rack to theyfree end ofthe pi'v-' oted cage 5.A As shown in the drawings' the rack Iconsists 'of two spaced' parallel 'mem-A bersV 14, 15, vjoined at suitableintervals by .Y

studs 16 having rotatable sleeves 17 thereon. rlhese studs together with their sleeves constitute the teeth of the rack, which teeth are the sprocket as having three Yseries of teeth, it is to be understood that the number of the series may be varied as (desired. vv.By employing a sprocket `having spaced series of teeth openings are provided between the series through which dirt and foreign matter maylmake its exit as will be quite clear from inspection of Fig. 2. It will be observed from an inspection of Fig2, that the side members 14;, 15, of the rack have a bearing upon lateral extensions 8i of the sprocket hub and "therack isthus guided in its reciprocation.

The rack is held in engagementwith its .fwheel and further guided in its reciprocation by means of a guide member surrounding the shaft-9 and formedfrom two 'substantially vtriangular plates 18,19, joined together 'at their apicesl and at their base corners by studs 20 having thereon rotatable sleeves 21. Those sleeves at the base ride on r theside members 14, 15, of the rack when the latter is reciprocated and hold the rack in engagement with the sprocket 8. l

Inforder to secure the rack tothe'v cage there is attached to the lower end of the rack j between its vside members 14, 15,` a, substantially triangggular saddle member 22 (Figs. 3v

and 4) adapted to rest at its'base edge on ak stud 23 located on the cage.` .The saddle member isheld upon the stud by means of a substantially semi-circularV clamping member 221,1'fo'rmed from two plates 25, 26heldin spaced relation by suitable cross-members 27, Theplat'es are each provided with perforated earsv28 adapted .to receive between themthe corners of the saddle 22 and to be` held in this position Vby `suitable means such as the stud 29 passing through the ears and f saddle landjheld therein by cotter pins 30.

The mode ofoperation of the Crusher herein described is well knownin the art and is clearly described in` the patent to Hiller,

above mentioned. From the above descrip` tion it yshould be clear that we have devised `a structure which is a marked improvement over prior devices of the character disclosed in the Hillerpatent, as crushers of this type yjustmentv of the cage. j v

3. In'a crushing andp'ulverizing machine,`

when provided with our improved adjusting j mechanism` arelessliable to become cloggedl with dirt and as afresult the cage may at all times beeasily manipulated.

While we have shown our improved adjusting mechanism as applied to a particular type of crusher it is to be understood that it may be used with other types in which similar adjustment is desired and that such modifications may be made therein as come within the scope of the following claims.

Havingthus described our invention, what j we claim is:

1. In a crushing land pulverizing machine,

the combination Awith a pivoted grinding cage of a beater element therein, an open faced, roller toothed" rack connected to the free end of said cage, arac'k wheelhaving aY ,seriesof teethv adapted to mesh Ywith said rack, and having clearance l'spaces oneach side ofsaid series of teeth between the same andthe sides of the rack forvtheclearance` of obstructing material, and means for oper- 1 ating the rackV wheel to positively move lthe rack for adjustment of the cage.f

2. In a'crushing and "ulverizlng machine,

the rcoi'nbination' Ywitha pivoted grinding cage, of a'beater element therein, an open faced rack'connected to the free end of said cage, a rack wheelhavingV a plurality of spaced parallel series of teeth Vin meshwith said rack, andmeans for operating the rack wheel Vto positively move therrack for .rad-l the combination. with a pivoted gr cage, of ay beater element therein,a rollerv itoothediackconnected to the'free end of* saidc'age, arack wheel havinga plurality of spaced parallel seriesof teeth in mesh with said rack, and means for operating the' rack wheel to positively move thejrack forv adjustment of the cage.

. i 100, v4:. In a crushing and'pulverizing machine, f f the combination with a ypivoted "giinding cage, ofv abeater element therein, an openy faced, 4roller toothed rackconnected' to the free end of 'said' cage, a rack Vwheel havinga plurality of 'spaced parallel seriesofv teeth" in mesh; `with said rack, and means for operating the rack` wheel Vto positively move "the Y' rack for adjustment of the cage.

In I testimony whereof, we have hereunto set our' hands in witnesses. v i 1 i, VWILLIAM HQHARTMAN. r GECRGHE W. BORTON. E Witnessesz. I y' SARA 17M. Riiavrir,` Y
